A brutal, purposefully obtuse roguelite first-person shooter 

You are one of the last humans fighting the Locus, a hyper-intelligent extra-dimensional species that has begun erasing all life on Earth and terraforming it into something beyond comprehension. Clear sectors, scavenge, upgrade, manage risk, and try not to die — you will die a lot.

  • Roguelite progression: randomized levels, enemies, rare loot,(eventual perks & bosses, each death can affect your game-play dynamically)

  • Greedy-meshed voxel chunks + ultra-cheap CSS pixellation shader for that brutalist retro look
  • Artifacts that affect gameplay in dramatic ways, powerful boons and debuffs from enemies and items.
